The 2019 NFL Draft is now just a few short weeks away, and there is still plenty of uncertainty about how things will play out. Just start at the top, for instance. For more than a month now, the Arizona Cardinals have been linked to Heisman Trophy-winning quarterback Kyler Murray with the first overall pick. Now the Cardinals are using their 30 pre-draft visits on players in contention for the top pick. That includes Ohio State defensive end Nick Bosa, who not too long ago was the consensus top selection. Are the Cardinals wavering, or just doing due diligence considering Bosa could be picked by NFC West rival San Francisco? Houston defensive tackle Ed Oliver is also getting an interview with Arizona, which would make sense in a trade-down scenario.
